Centrifugal wet type air cleaner utilizing a spin vaporizer and a spiral on the basis of a labyrinth effect

ABSTRACT

This invention relates to a wet type centrifugal ‘filter less’ air cleaner. The air cleaner includes a housing having a scrubbing room associated with an air inlet and a vortex room associated with an air outlet. A reservoir is in fluid communication with the housing for supplying washing water to the air cleaner. An atomizer is in cooperation with the reservoir for producing atomized washing water to form a wet air mixture in the scrubbing room so that the atomized washing water collects the contamination in the air. A centrifugal impeller is disposed in the housing for drawing in air to create a centrifugal force on the wet air mixture. As the wet air mixture flows through the vortex room the centrifugal force separates the contaminated washing water from the purified air because of the difference between the specific gravities of the air and the washing water.
